Intel strikes me as a completely dysfunctional company.
To your point, it's not so much dysfunction as it is lack of interest in ensuring both drivers for windows and Linux are on par. There is no reason why they should not be. It's definitely a black eye for Intel to have a 3rd party vendor identify major gaps between their drivers like this. If I were a manager at Intel, right about now I'd ask that whatever test suites they use to prove out the Windows' driver performance be completely ported over to Linux to test their Mesa driver. Anything short of this feels like they are merely placating the open source community/developers.

Originally posted by zanny View PostI have a 7870, I've used 6000 series cards, and I've built and run 3 r600 / radoensi APUs. The only time radeonsi ever crashes is in extremely new games, and very rarely, but example I got one crash in ~80 hours of borderlands 2 and it was due to a firmware bug on the card that got fixed a week later.
Catalyst, on the other hand, is lucky to last an afternoon.

Originally posted by gigaplex View PostI had a look through that bug report. It quickly devolved into a dumping ground of "me too" reports of unrelated issues. They couldn't get a clear, consistent answer on which kernels were actually affected, so where would the bisection start?

Then came a company who actually cares and hires someone who has a clue, and they end up pointing out: guys, you forgot the handbrake on.

Ever since Linux 3.14 and the new radeonsi firware there is a random crash bug that hasn't been fixed so you either have an old kernel or a older linux firmare (that technically was 600) or are lying. I had to go back to catalyst for stablity (which hasn't crashed once).
I myself hadn't had a problem with the radeon driver for maybe 3 or 4 years, but I didn't game much with it.

Originally posted by jaxxed View PostEasy now guys. The truth is that the FGLRX is stable for some cards/games, but unstable for others ... the FOSS drivers are also stable for some, but not for others. If you read the forums enough you'll notice that.

And then there are the AMD guys who don't (have time to) benchmark at all.
My guess is, if you want performance to match the Windows driver you will have to figure out it by yourself, like the Lunar guys did.

Originally posted by TheAaronB123 View PostHard to bisect something that takes 5 minutes to 3 days to arise. I am the OP to bug 61844 for Mesa's RadeonSI random crashes. Why don't you go ahead and bisect it for me over an entire month, even if it is because of a single commit? Be reminded it's not known clearly to be Mesa, or a kernel update that shows it, or anything else. I personally think it's DMA issues of some sort, but I'm also not a kernel/AMD dev. Still, besides this bug for me, RadeonSI is fine on my R9 270X. But this bug is bad. And it's been a problem for about 3 months now. Other than that, most games run fine with everything on Ultra: Civ 5, The Witcher, tons of valve games. Rust has major engine issues with it being a POS, but most games programmed well are just fine.
